Light source unit for an imaging device and method

Abstract

A light source unit for an imaging device includes a beam extraction unit configured to receive broadband laser light, to direct at least a part of the broadband laser light having a first wavelength into an amplifier beam path, and to direct a residual laser light into a first illumination beam path. The light source unit further includes an optical amplifier unit arranged in the amplifier beam path and configured to generate amplified laser light having the first wavelength by amplifying the part of the broadband laser light, and a frequency changing unit arranged in the amplifier beam path and configured to generate laser light having a second wavelength from the amplified laser light having the first wavelength.
